Robot Reconnoiters Uncharted Terrain

Mobile robots have many uses. They serve as cleaners, carry out inspections and search for survivors of disasters. But often, there is no map to guide them through unknown territory. Researchers have now developed a mobile robot that can roam uncharted terrain and simultaneously map it ? all thanks to an algorithm toolbox. Industrial robots have been a familiar sight in the workplace for many years. In automotive and household appliance manufacture, for example, they have proved highly reliable on production and assembly lines. But now a new generation of high-tech helpers is at hand: Mobile robots are being used in place of humans to explore hazardous and difficult-to-access environments such as buildings in danger of collapsing, caves, or ground that has been polluted by an industrial accident. Equipped with sensors and optical cameras, these robots can help rescue services search for victims in the wake of natural disasters, explosions or fires, and can measure concentrations of hazardous substances.
